Green Synthesis of Gold and Silver Nanoparticles Using Averrhoa bilimbi Fruit Extract

Journal of Nanotechnology, 2013
We report on rapid one-step green synthesis of gold and silver nanoparticles using fruit extract of Averrhoa bilimbi Linn. UV-Vis absorption spectroscopy was used to monitor the quantitative formation of gold and silver nanoparticles. The characteristics

Interaction of (-)-epigallocatechin gallate with silver nanoparticles [PDF]

arXiv, 2010
Interactions between silver nanoparticles and (-)-epigallocatechin gallate (EGCG) have been investigated. Prior to the addition of EGCG molecules the silver particles are stabilized by borate ions. Studies on the surface plasmon resonance band of silver particles suggest that the EGCG molecules remove the borate ions from the surface of the metal ...

Unlocking High‐Performance in All‐Organic Solar Cells by the Development of Organic Electrodes with No Acid and High‐Temperature Treatment and the Effective Preparation Thereof on Organic Multilayer Films

Advanced Functional Materials, EarlyView.
The developed all‐organic solar cells achieve a power conversion efficiency of 8.7%, more than double the previous record. In addition, bioplastic substrates are used to produce environmentally friendly solar cells with an efficiency of 8.6%. These results are achieved by developing high‐performance organic electrodes without acid doping or high ...

Stabilization of DAPI in Base-Catalyzed Sol-Gels Using Surface Enhanced Raman Spectroscopy [PDF]

, 2017
Sol-gels can be used as substrates for sensory materials in solutions. A fluorescent dye that binds to DNA, 4’,6-diamidino-2-phenylindole (DAPI), could be used as a biosensor for a solution.

Synthesis Procedures for Silver Nanoparticles [PDF]

Engineering International, 2014
This article gives some proposals on how to grow silver nanoparticles using different methods. Dilute silver salts are recommended as the metal precursor starting solutions. The formation of the silver nanoparticles is to be monitored using UV-Vis absorption spectroscopy so as to reveal the formation of silver nanoparticles and how they will exhibit ...

Hierarchically Engineered Triple‐Defensive Antifouling Coating with Well‐Regulated Structure for Enhanced Wastewater Treatment

Advanced Functional Materials, EarlyView.
Inspired by shark skin, which has a hydrophilic “denticle layer” and a low surface energy “mucus layer,” a triple‐defense antifouling coating is developed. This coating features a robust hydrophilic catalytic nanoparticle layer overlaid with dispersed hydrophobic perfluoro‐silane domains, optimizing fouling resistance, release, and degradation for ...
